Gibson and his attorney Blair Berk have met previously with Los Angeles Sheriff's Department officials and the Los Angeles District Attorney to discuss what Mad Mel says was extortion on the part of Oksana.

The investigation is still ongoing but is rapidly coming to a head.

The Oscar winning Braveheart director/actor is being investigated for domestic violence against Oksana and that investigation appears close to wrapping up.

"There is simply no smoking gun that point to Oksana trying to extort Mel," the source said.

"There are emails which Gibson's camp say is clearly extortion."

But those emails can also be viewed in the context of an ongoing negotiation between Mel and Oksana regarding custody of their infant daughter.
